DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 and FIG. 2, the present invention is to provide a shelf structure for loading computer equipment, which comprises at least more than four vertical beams: a first beam 10, a second beam 10′, a third beam 20, and a fourth beam 20′. On surfaces of one side of the first, second, third, and fourth beams 10, 10′, 20, 20′ are provided with a plurality of positioning holes 35, respectively. Referring to FIG. 3, at least more than one shelf 40 is composed of the following parts: an inner arm 45 whose board surface is provided with at least more than one long groove 451, and whose side end is formed with a vertical board surface 452 on which is installed with at least more than one protruded hook 453 and at least more than one screw hole 454; an outer arm 46 whose board surface is provided with more than one screw hole 461, and whose side end is formed with a vertical board surface 468 on which is installed with protruded hooks 463 and screw holes 464; bolts 47 which are transfixed into the long grooves 451 and are screwed into the screw holes 461 of outer arm 46, such that the inner arm 45 and the outer arm 46 are screwed, fixed, and provided with a pre-determined assembly length; bolts 48 which are transfixed into the screw holes 454 on the vertical board surface 452 of the inner arm 45, and are screwed into the positioning holes 35 of the third and fourth vertical beams 20, 20′, with the hooks 453 being locked into the positioning holes 35 of the third and fourth vertical beams and the vertical board surface 452 of inner arm 45 being fixed on the third and fourth vertical beams 20, 20′ (as shown in FIG. 8); bolts 49 which are transfixed into the screw holes 464 on the vertical board surface 468 of the outer arm 46, and are screwed into the positioning holes 35 of the first and second vertical beams 10, 10′, with the hooks 463 being locked into the positioning holes 35 of the first and second vertical beams 10, 10′, and the vertical board surface 468 of the outer arm 46 being fixed on the first and second vertical beams 10, 10′ (as shown in FIG. 8).

Referring to FIG. 3 and FIG. 4, a rim surface of the screw hole 461 of outer arm 46 is formed with a projection body 462, and a surface at one side of the long groove 451 of inner arm 45 is formed with a concave part 405, with the projection body 462 being fitted into the concave part 405.

Referring to FIG. 3 and FIG. 4, a board surface of the inner arm 45 is provided with a concave surface 455 of a larger area and longer length, whose interior is provided with a screw hole 456. The outer arm is provided with a long projection body 465 on which is formed with a long groove 466, and the long projection body 465 can be fitted into the concave surface 455. A bolt 457 is screwed into the long groove 466 and the screw hole 456.

Referring to FIG. 3, a side edge of the outer arm 46 is bended with a frame edge 467 which is bended at about 90 degrees, whereas a side edge of inner arm 45 is bended with a frame edge 458 which is bended at about 90 degrees.

Referring to FIG. 2 and FIG. 3, the concave surface 455 of the inner arm 45 is extended forward to form a long concave part 459 of a smaller area, and a front section of the long projection body 465 on the outer arm 46 is tightly fitted into the long concave part 459.

Referring to FIG. 1 and FIG. 2, spacing between each of the first, second, third, and fourth vertical beams 10, 10′, 20, 20′ has been standardized. An assembly length L of the shelf 40 is adjusted according to the specified spacing, such that a length of shelf 40 can be compatible with a length (width) between the first and third vertical beams 10, 20, and be compatible with a length between the second and fourth vertical beams 10′, 20′. Referring to FIG. 3, FIG. 4, and FIG. 5, there are four long grooves 451 in the inner arm 45, which are symmetrically located on a board surface of inner arm 45 in an equal distance. Two bolts 47, (47) are transfixed into the two long grooves 451, (451), and are further screwed into two screw holes 461, (461). The bolts 47, (47) are in a loose status.

The other two bolts 47, (47) are transfixed into the other two long grooves 451, (451), and are screwed into the other two screw holes 461, (461). These bolts 47, (47) are also in a loose status. According to an adjustment of assembly length of the inner arm 45 and the outer arm 46, four bolts 47 are shifted relatively in the four long grooves 451, respectively. The long projection body 465 is shifted transversally in the concave surface 455. After setting the assembly length of inner and outer arms 45, 46, a user can transfix and screw the four bolts 47 into the four screw holes 461, and screw one bolt 457 into another long groove 466 and screw hole 456, thus the inner arm 45 and the outer arm 46 will be tightly and firmly screwed into one body. Referring to FIG. 5, the projection body 462 is in a cone shape and can be latched into the concave part 405, the long projection body 465 is extended into the long concave part 459 to form a tight fitting (as shown in FIG. 4), and the other two cone-shaped projection bodies 462 are latched into the concave part 405 for forming a tight fitting, thereby enabling the inner arm 45 and outer arm 46 to be perfectly rigid and not loosened under a long term condition for sustaining with a load, after being screwed and fixed.

Referring to FIG. 8, the shelf 40 after being assembled is locked into the positioning holes 35 of the third and fourth vertical beams 20, 20′ with the hooks 453 at a left side. The bolts 48 are screwed into the positioning holes 35 and the screw holes 454 and the hooks 463 at a right side are locked into the positioning holes 35 of the first and second rectangular frames 10, 10′. Next, the bolts 49 are screwed into the positioning holes 35 and the screw holes 464. Accordingly, an entire shelf 40 will be firmly positioned on the first and third vertical beams 10, 20 (as shown in FIG. 1), whereas another shelf 40 is firmly positioned on the second and fourth vertical beams 10′, 20′ (as shown in FIG. 2), to serve as transversal beams between the first, third vertical beams 10, 20 and the second, fourth vertical beams 10′, 20′. A number of quantities of the shelves 40 positioned on the first, second, third, and fourth vertical beams 10, 10′, 20, 20′ are dependent upon a number, volume, and weight of computer cases to be loaded.

Referring to FIG. 6, L1 is an assembly length of the inner and outer arms 45, 46 after they are assembled and fixed; whereas L2 in FIG. 7 refers to an assembly length of the inner and outer arms 45, 46 after they are assembled. The assembly length L1 of FIG. 6 is larger than the assembly length L2 of FIG. 7. In other words, the assembly length of inner and outer arms 45, 46 can be quickly controlled to cope with a working width between the first, second, third, and fourth vertical beams 10, 10′, 20, 20′ of different specifications.

Referring to FIG. 9, a plurality of shelves 40 is positioned and fixed on the first, second, third, and fourth vertical beams 10, 10′, 20, 20′ to form a framework 100, wherein an exterior side of the first, second, third, and fourth vertical beams 10, 10′, 20, 20′ is respectively fixed with a fixing frame 90 which is used to support and position the first, second, third, and fourth vertical beams 10, 10′, 20, 20′. Two side edges 82 at a bottom of computer case 80 (as an imaginary line in FIG. 9) are located on surfaces of frame edges 467.

Referring to FIG. 2, a design of frame edge 458 of inner arm 45 can enhance an overall strength of the inner arm 45 for sustaining with a load. As shown in FIG. 9, the frame edges 467 are used to load the computer case 80 which can be a heavy and large case. As the shelves 40 are provided with higher strength for sustaining with a load, they can be effectively loaded with the computer case 80.

The shelves 40 of present invention are provided with a quick and convenient assembling into and disengaging from the framework 100, a high strength for sustaining with a heavier or larger computer case 80, and a quick adjustment of assembly length, upon installing on the first, second, third, and fourth vertical beams 10, 10′, 20, 20′. If the entire framework 100 needs to cope with an installation and a change of positions of the industrial computer cases 80 of different specifications, the positions of shelves 40 in the framework 100 can be quickly adjusted, thereby being able to be loaded with the computer cases 80 in different sizes.
